The weekend will be more like summer and temperatures might reach the low 90s on Sunday, the Capital Weather Gang says. Good conditions will prevail for Capital Pride events, community festivals like Make it Mount Pleasant, weekend getaways and the traffic and transit projects that may slow you down.

Springfield Interchange

On Friday night, the Virginia Department of Transportation plans to close all lanes of I-395 North near the Springfield interchange. The closing, part of the 495 Express Lanes project, is scheduled to start at 9 p.m. and continue until 7 a.m. Saturday. Workers will be putting down pavement stripes for a traffic shift.

That night, I-395 North traffic will be detoured to Exit 170 (the Beltway’s inner loop). Drivers will swing around at Exit 52A and get back on the Beltway to Exit 57B for I-395 North. The traffic delays are likely to add about 20 minutes to regular travel times.

Beltway/Gallows Road

VDOT also plans to close Gallows Road (Route 650) at the Beltway from 10 p.m. Saturday until 9 a.m. Sunday during installation of an overhead sign. Emergency vehicles will be permitted through the work zone to maintain access to INOVA Fairfax Hospital. Beltway drivers using Exit 51 for Gallows Road also can reach the hospital. Other drivers will face a detour.

This work and the work at the Springfield interchange are part of the 495 Express Lanes project.

Gay Pride events

The annual Capital Pride parade is scheduled to begin at 4:30 p.m. Saturday. The paraders begin at 22nd and P streets NW, go through Dupont Circle, up New Hampshire Avenue to R Street, then turn south on 17th Street, make a left on P Street, then turn right on 14th Street and end north of Thomas Circle. See a route map on the Capital Pride Web site.

The nearest Metro station is Dupont Circle on the Red Line, but note the Metro weekend delays listed below.

The Capital Pride Festival is scheduled for 11 a.m. to 6 p.m. Sunday on Pennsylvania Avenue NW between Third and Seventh streets, near the U.S. Capitol grounds. The nearest Metro stations are Archives on the Green and Yellow lines and Judiciary Square on the Red Line.

Metro weekend delays

Metro’s rebuilding program will affect service on four of the five lines from 10 p.m. Friday through the train system’s midnight closing Sunday.

Orange Line: Free shuttle buses will replace trains between East Falls Church and West Falls Church. Trains will operate between Vienna and West Falls Church and between East Falls Church and New Carrollton on their regular weekend schedules, but allow about 20 minutes of extra travel time for the bus connection.

Crews are working on the connection to the new Silver Line. They will be doing similar work the weekend of June 23-24.

Blue Line: Trains will share a track between Stadium-Armory and Addison Road. They are scheduled to leave Largo Town Center and Franconia-Springfield every 20 minutes. Add about 15 minutes to normal travel times for the work zone disruption.

Red Line: Trains will share a track between Takoma and Forest Glen. They are scheduled to operate every 20 minutes through the weekend, but add about 10 minutes of extra travel time to get through the work zone.

Between 9 a.m. and 9 p.m. Saturday and Sunday, additional trains will operate between Shady Grove and New York Avenue. Along that part of the line, outside the work zone, trains should appear at platforms about every 10 minutes.

Green Line: Green Line trains will share a track between College Park and Greenbelt. They will operate on their normal weekend schedules, Metro says, but every other train will terminate at College Park rather than Greenbelt. Riders traveling to or from the Greenbelt station should add about 15 minutes to their normal travel times, the transit authority says.

Beltway/Telegraph Road

Beltway drivers in Virginia won’t experience the extensive delays of last weekend near the Wilson Bridge, but work continues on the inner loop LOCAL lanes.

Until July 1, only one inner loop LOCAL lane will be open. During this time, drivers on the inner loop THRU lanes won’t be able to exit at the Eisenhower Connector. Drivers bound for Eisenhower Avenue will need to exit farther west at the Van Dorn Street interchange.

All the inner loop work between Route 1 and the Eisenhower Connector is scheduled to be done by July 2, leaving two THRU lanes and two LOCAL lanes in their final alignment.

But later this month, the outer loop will go through a major change. On the weekend of June 15-18, project managers plan to shift the THRU/LOCAL split to just west of the Eisenhower Connector, after the Van Dorn Street exit. This is for the final paving of the lanes.

After the split is repositioned, the THRU lanes will be in their final alignment, but until July 23, there will be only one LOCAL lane from the split to just past Telegraph Road. Then, all the outer loop lanes will be open in their final configuration.

The repositioning of the split and the change in the lane pattern probably will cause extra traffic congestion in a zone that already slows traffic significantly.

D.C. speed cameras

For those who might visit D.C. only on weekends: There are several dozen new locations for speed cameras, and they began issuing real tickets this week after a month of sending out warning notices.

The locations are all over the District, and the speed limits in those areas range from 25 to 40 mph. But I think the location that might get particular attention from drivers is on the Southwest Freeway (Interstate 395) near Exit 4, on both sides of the highway. The speed limit there is 40 mph.

Metro Rush Plus guides

Besides delayed trips, this week’s Metro riding experience has included a barrage of information about the new Rush Plus service, which starts June 18. The maps aboard trains have been updated to show where trains will be added for the morning and afternoon commutes, stickers on the fare gates tout the service and brochures are being handed out.

Look for my user’s guide to Rush Plus on our Commuter page this Sunday. Then let’s discuss it during my online chat at noon Monday.

Chesapeake Bay Bridge

A summer travel season reminder: The best times to use the Bay Bridge are Thursdays and Fridays before 10 a.m. and after 10 p.m., Saturdays before 7 a.m. and after 5 p.m., and Sundays before 10 a.m. and after 10 p.m.
